反応手順

A solution of 4-(trifluoroacetylamino)cinnamic acid (1.30 g) and 3-(aminomethyl)pyridine (540 mg) in 20 ml dimethylformamide was mixed with 0.9 ml diethyl cyanophosphate and subsequently with 0.8 ml triethylamine on ice, and then stirred at room temperature for 4 hours. The solid precipitated from water was then filtered, washed with water, and dried by heating under reduced pressure to give N-(3-pyridylmethyl)-4-[(trifluoroacetyl)amino]cinnamamide (1.61 g, 92%).
